Abstract

PURPOSE:To make a dimensional precision confirmation operable while in processing cycle, by automatically confirming a dimensional precision of processing face of the work, with a processing work completed, with a contact detecting measuring piece used, when commanded a confirmation of the dimensional precision by NC data. CONSTITUTION:With a coil 20 excited by an AC power source 19, a current is induced in an induction current path (as shown by broken lines in the drawing) made by the contact between a hole, provided in a work W, and a measuring piece TS, and this induced current is detected by a contact detecting circuit 3 with its output fed to a NC device main unit 2 to control servo motors 14-16. In the above device, is additionally provided a dimensional precision approval device 4. This device 4, when generated an approval command for dimensional precision, with a position, located from the measured surface by a prescribed distance apart, determined to the reference point of dimension measurement, makes a shifting of the measuring piece TS toward the measured surface from this reference point, and the constitution is so constructed with a confirmation of the dimensional precision approved by said shifting distance.
